Definitions
- the present invention relates to a wind turbine with an asynchronous machine for determining the azimuth position of the machine house of the wind turbine, wherein the asynchronous machine is equipped with a first rotor / stator assembly in which the rotor is directly connected to a shaft.
- Asynchronous machines are well known for a long time, for example WO 98/40958 . DE 32 34 673 . WO 90/13937 . US 5,838,135 and are used for a variety of drive or setting tasks.
- An actuating task is often the process of a machine part from a starting position to a predefinable, new target position.
- An exemplary application is the adjustment of the azimuth position in wind turbines.
- the azimuth position namely the orientation of the nacelle in horizontal axis systems
- the rotor can be tracked to the wind, so as to be able to generate continuous electrical energy.
- the nacelle of such a wind turbine is rotatably mounted and is moved over at least one so-called azimuth engine.
- This method is carried out by, for example, a drive pinion engages in a toothing on the tower head and adjusts the nacelle by operating the motor relative to the tower head.
- the asynchronous machine is stopped.
- the DE 199 20 504 A1 shows an azimuth drive for wind turbines with four three-phase asynchronous motors, each having a rotor / stator assembly, which are electrically isolated from each other. Each rotor of each of the four three-phase asynchronous motors acts independently of each other on a ring gear arranged on the sprocket via its own shaft.
- Another azimuth drive for wind turbines in the manner described above is from the EP 0 945 613 A2 known.
- the azimuth position is not changed with every arbitrarily small deviation in the wind direction. This results in small wind direction changes to an oblique flow of the rotor and a resulting yaw moment about the vertical axis of the wind turbine to the nacelle. So that this yaw moment does not lead to an unwanted change in the azimuth position, the azimuth motors can be acted upon by a direct current in order to generate a corresponding braking torque.
- Object of the present invention is therefore to provide a drive for detecting the machine house of a wind turbine, the drive allows cancellation of the game of mechanical components in the predetermined target position, without causing mutual interference between the desired braking torque and the elimination of the Game is coming.
- asynchronous machine has a second rotor / stator assembly, which is, however, electrically separated from the first rotor / stator assembly, wherein the rotor of the second rotor / stator assembly is also directly connected to the shaft.
- a rotor / stator assembly can be supplied with a direct current in the desired direction to produce a desired braking torque, while the second rotor / stator assembly is subjected to an alternating current, which generates a torque in the direction of the rotating rotating field and thus causes an actuation of the drive.
- each of the drives can be adjusted by the opposite direction of the torque so as to overcome the range of mechanical play. This eliminates the mechanical game.
- both rotor / stator assemblies of the drive are applied in phase with a first alternating current when adjusting a machine part.
- the reference numeral 10 denotes a drive motor according to the invention.
- This drive motor has a first rotor 12, which is connected to the shaft 20, and a first stator 14, which cooperates with the first rotor 12.
- the drive 10 according to the invention has a second rotor 22, which is also connected to the shaft 20, and cooperates with the stator 24.
- the two rotor / stator assemblies 12, 14; 22, 24 are combined in this embodiment in a housing, but electrically separated from each other. This is illustrated by the connection terminals 15, 25 shown separately.
- FIG. 2 shows a further embodiment of the present invention.
- the rotor / stator assemblies 12, 14; 22, 24 each housed in a separate housing 10, 18. Both, however, act as in the FIG. 1 shown embodiment, on the same shaft 20, which passes through the housing 10 of the first rotor / stator assembly 12, 14 and into the housing 18 of the second rotor / stator assembly 22, 24 engages and connected to the two runners 12, 22 is.
- Fig. 3 shows a schematic arrangement of four azimuth drives an adjustment on the nacelle of a wind turbine.
- Wind turbines usually have an active drive for the wind direction tracking. This rotates the machine head of the wind turbine so that the rotor blades of the rotor are optimally aligned in the direction of the wind.
- the active drive for the wind direction tracking is an azimuth drive 1 with the associated azimuth bearing 2 and is usually located between the tower head and the nacelle of the wind turbine.
- a single azimuth drive is sufficient, larger wind turbines are usually with multiple drives, eg four drives, as in Fig. 3 shown, equipped.
- the four drives 1 are evenly distributed over the circumference of the tower head 3 (also an uneven distribution is possible).
